Open Stack

Perhaps 512MB is a bit tiny, but I have a reasonable Juno cluster running in
1GB VMs on a 6GB laptop - controller, Neutron network, 2 compute nodes (one
of them 2B), 2 storage nodes. I can boot instances, generate some network
load, attach volumes. The storage is 10GB each or so. Number of CPUs doesn't
matter. I haven't installed Heat, Swift, Ceilometer and other goodies.

I feel the specs should be as low as possible, so that we don't scare off
people who want to learn OpenStack.
	
If you think proof of concept requires more, why not publish two sets of
recommendations, one for learning, the other for more serious work?

Subject: [OpenStack-docs] [install-guide] minimal requirements for a
proof-of-concept environment

At the moment we mention the following minimum requirements for a
proof-of-concept environment in chapter 2 (basic environment):

---snip---
Controller Node: 1 processor, 2 GB memory, and 5 GB storage

Network Node: 1 processor, 512 MB memory, and 5 GB storage

Compute Node: 1 processor, 2 GB memory, and 10 GB storage
---snap---

Does this really work? Has anybody tried to run a network node with only
512 MByte memory? Or a controller node with RabbitMQ, MySQL, MongoDB and a
lot of OpenStack services with 1 VCPU and 2 GByte memory?

I would propose to increase the minimum requirements:

Controller Node: 4 processors, 8 GB memory, and 15 GB storage Network Node:
2 processors, 4 MB memory, and 10 GB storage Compute Node: 2 processors, 4
GB memory, and 20 GB storage

Christian.
